I'm scripting a backup solution, the line that does the business looks
like this:
tar -zcvf - * --exclude-from $EXCLUDES | openssl des3 -salt -k $1 |
dd of=$(hostname)-$(date +%Y%m%d).tbz
Because of the "v" flag tar writes to stdout the name of each file
copied. How can I get that output redirected to a variable, to use
later in the script?
Thanks!
Use $() like you do with the date command. You have to redirect stderr
back to stdout, which means running it in a subshell:
FILES=$( ( tar -zcvf - * --exclude-from $EXCLUDES | openssl des3 -salt
-k $1 | dd of=$(hostname)-$(date +%Y%m%d).tbz ) 2>&1 )
It may cause unexpected results if there're spaces in the filenames though.
